Removing bitnami

Hi,

I guess that is what you're looking for in the official documentation: https://docs.aws.amazon.com/lightsail/latest/userguide/amazon-lightsail-remove-bitnami-banner.html

Best,

While it's not possible to completely remove Bitnami from a Lightsail WordPress server, you can remove the Bitnami banner that appears on some Bitnami blueprint applications. This banner is typically displayed in the bottom-right corner of the application's home page.

To remove the Bitnami banner:

1. Connect to your Lightsail instance using the browser-based SSH client.
2. Run the Bitnami Configuration Tool (bnconfig) to disable the banner.
3. The tool will disable the banner and restart the necessary services (Apache or the specific application).
4. You can verify the removal by visiting your instance's public IP address in a web browser.

It's important to note that not all Bitnami blueprint applications display this banner, so you should first check if it's present on your instance's home page.

If you're looking to make more significant changes to your WordPress setup or move away from the Bitnami stack entirely, the recommended approach would be to launch a new Lightsail instance with a fresh WordPress installation and migrate your existing site data to it. This method allows you to start with a clean slate and have more control over the software stack, but it requires more effort in terms of data migration and configuration.
